The topic at hand is about finding a bed or mattress that is comfortable and accommodating for people with an ostomy, especially those who prefer sleeping on their stomachs. Here are some ideas and insights shared by others:

1. The idea of cutting a hole in a foam mattress has been tried, but it only partially works and makes using fitted sheets difficult.

2. An "Ostomy Support Body Pillow" is available online, but some find it overpriced, uncomfortable, and easy to roll off during sleep.

3. A modular foam bed with removable blocks could be a solution, as removing the block beneath the pouch might help. However, the cost is a significant barrier.

4. There is curiosity about whether a waterbed would press the pouch against the body when sleeping on the stomach.

5. Two innovative concepts for inspiration include:
- An Intelligent Mattress made of removable foam blocks.
- An Inflatable Air Mattress with a pump designed for post-operative comfort.

Advice and insights from others include:

- The Ostomy Support Body Pillow can be arranged to limit rolling and used for stomach sleeping with an extra pillow after six weeks post-op. However, its velour cover might feel too warm.

- Waterbeds have been used successfully by some ostomates, providing minimal pressure on the pouch and allowing easy movement during sleep.

- Adjustable solutions like a riser-recliner chair or an adjustable bed can keep the sleeper semi-upright, limit rolling, and help manage output and reflux.

- Pillow configurations can also help:
- Using wedges to elevate the torso can reduce nighttime ballooning, though it generally confines you to back sleeping.
- A technique learned at the Mayo Clinic involves using pillows under the head, between the legs, and wedged behind the back for stable positioning.
- For severe rib pain or restlessness, the same pillow arrangement or an adjustable bed can prevent painful rolling.

- A custom neck pillow idea involves using a polystyrene-filled travel neck pillow, which, after repeated washing, reduces bead size and creates slack. The center could be modified to create a soft void for a stoma if needed.

- Concerns about sectional or block mattresses include their high cost and limited usefulness if the sleeper moves around a lot.
